Can you call esri ArcGIS maps through a web service like Google? I remembering seeing an old QlikTech presentation that says that any other type of GIS integration involves alot of time and risk so it is not recommended.
Re: How can maps be added to a QlikView dashboard?
GIS/Maps Analytics in QlikView is a very interesting topic indeed but there are many technical limitations using Google Maps (GMaps) to display QlikView KPI indicators. Indeed, you cannot display several indicators at the same time and on the same map (background + foreground indicators), you are also limited to bubbles and therefore cannot display pie/bar charts nor "real" heat maps. On top of that, you cannot display QlikView KPIs on specific Sales/Business Areas with GMaps such as the Bricks in the Pharmaceutical sector (Brick = aggregation of zipcodes).
Moreover, there are also a few "commercial" aspects to be considered since many QlikView customers & channel partners use GMaps API "FREE" Key inside their QlikView server or rich client without complying with GMaps license terms...Indeed, for "professional internal use" (intranet, extranet or internet with username/password authentication to QlikView application), you must buy GMaps API "Premier" which costs about 10,000 $ USD per year or 8,500 euros per year + possible extra fees depending upon the total number of daily hits.
A few alternatives exist such as Open Street Map (totally FREE) or other WMS/TMS services. I suggest you to have a look at our new mapping extension for QlikView 11 SR1 namely "GeoQlik v11.6":
